April 24 (UPI) — The creator of Dutton Ranch has left the series prior to the show’s premiere.

Variety and The Hollywood Reporter said Friday that creator, executive producer and showrunner Chad Feehan has exited the show ahead of its series premiere in May.

Sources told Deadline Feehan delivered as a writer but had challenges handling the cast.

Dutton Ranch is a spinoff of the Paramount Network series Yellowstone, created by Taylor Sheridan. Kelly Reilly and Cole Hauser reprise their roles as Beth Dutton and Rip Wheeler.

“As Beth and Rip fight to build a future together — far from the ghosts of Yellowstone — they collide with brutal new realities and a ruthless rival ranch that will stop at nothing to protect its empire,” an official synopsis reads.

Other cast members include Ed Harris, Annette Bening, Jai Courtney and Natalie Alyn Lind.

Dutton Ranch will have a two-episode premiere May 15 on Paramount+ and Paramount Network.
